Source: Laboratory of Alan Lester - University of Colorado Boulder Igneous rocks are the products of cooling and crystallization of magma. Volcanic rocks are a particular variety of igneous rock, forming as a consequence of magma breaching the surface, then cooling and crystallizing in the subaerial environment. Magma is molten rock that typically ranges in temperature from approximately 800 °C to 1,200 °C (Figure 1). Magma itself is produced within the Earth via three primary melting...

Surface Tension of Fluid

Surface tension is a fundamental property of fluids, occurring at the boundary between a liquid and a gas or between two immiscible liquids. This phenomenon arises from the cohesive forces between molecules at the fluid's surface, creating an effect similar to a stretched elastic membrane. Inside each fluid, molecules are equally attracted in all directions by neighboring molecules, but surface molecules experience a net inward force, resulting in surface tension. Surface tension varies with...

Source: Laboratory of Alan Lester - University of Colorado Boulder Igneous rocks are products of the cooling and crystallization of high temperature liquid rock, called magma. Magmatic temperatures typically range from approximately 800 °C to 1,200 °C. Molten rock is, perhaps luckily for humans, an anomaly on planet Earth. If a random and imaginary drill hole were made in the Earth, it would most likely not reach a region of truly and totally molten material until the outer core, at nearly...

Determining Spatial Orientation of Rock Layers with the Brunton Compass

2023
Source: Laboratory of Alan Lester - University of Colorado Boulder Most rock units exhibit some form of planar surfaces or linear features. Examples include bedding-, fault-, fracture-, and joint-surfaces, and various forms of foliation and mineral alignment. The spatial orientation of these features form the critical raw data used to constrain models addressing the origin and subsequent deformation of rock units. Although now over 100 years since its invention and introduction, the Brunton...

A 3D system of culturing human articular chondrocytes in high levels of synovial fluid is described. Synovial fluid reflects the most natural microenvironment for articular cartilage, and can be easily obtained and stored. This system thus can be used for studying cartilage regeneration and for screening therapeutics for treating arthritis.
FAQs
Wettability and interfacial tension influence capillary pressure, fluid retention, and the distribution of liquids and gases within geological materials. Together, they help determine how readily fluids move through pore spaces when more than one phase is present. Engineering predictions therefore require these properties to estimate flow behavior and containment in subsurface systems.
Surface chemistry and roughness affect how fluids interact with mineral grains, including the extent to which fluids are adsorbed or retained. Because these characteristics also influence interfacial tension, they can modify the conditions governing fluid movement and storage. Characterizing both properties provides a more complete basis for evaluating fluid behavior in geological materials.
Mineral composition affects the reactions that occur when fluids contact rock, including dissolution and precipitation. These reactions can alter the mineral surfaces and the pathways available for flow, making permeability an important outcome to predict. In engineering systems, accounting for mineral composition helps evaluate how fluid-rock interactions may change subsurface performance over time.
A useful characterization considers surface chemistry, mineral composition, roughness, and wettability, together with their effects on adsorption, interfacial tension, and capillary pressure. Evaluating these linked properties helps connect surface behavior with fluid movement, retention, and reaction. The resulting information supports predictions of permeability, mineral alteration, and long-term fluid containment.
These measurements are important when engineers must predict how injected or naturally occurring fluids move, react, or remain contained underground. In groundwater remediation, they help assess subsurface fluid behavior, while in carbon storage they support evaluation of retention and long-term containment. The same surface properties also inform assessments of mineral alteration and permeability.
Characterizing fluid-rock interactions helps engineers evaluate how geological materials will respond to fluids in petroleum reservoirs, geothermal systems, and hydraulic fracturing. Surface properties provide context for predicting multiphase flow, adsorption, capillary pressure, dissolution, precipitation, and permeability changes. These predictions can guide assessment of system performance, fluid containment, and the effects of mineral alteration.
